Biology Question and Answers

This document discusses three questions related to critical thinking. Question 1 discusses non-steroid hormones, which produce fast but short-lived responses through signal transduction mechanisms. Question 2 discusses prostaglandins, which act locally as tissue hormones rather than circulating through the bloodstream. Question 3 discusses antidiuretic hormone (ADH), which maintains blood volume, urine concentration, and tissue water levels by increasing water permeability when the body is dehydrated.

Q1

The non-steroid hormones are the types of hormones which would be the most

appropriate for all sorts of large-scale, fast, but rapidly declining responses. The choice of this

hormone is mainly as a result of the second messenger mechanism associated with its signal

transduction. The mechanism triggers the cascade effect, which considerably amplifies the

impact of the hormone. In comparison to steroid hormones, the impacts of this hormone may

occur within seconds, while those of steroid hormones may take several hours or days. However,

while the full effects of non-steroid take effects fast and in large scale, they also decline at a

rapid rate.

Q2

Prostaglandins are some of the most popular unsaturated carboxylic acids that are

synthesized biochemically from arachidonic acid, a fatty acid (Bettelheim et., 2015). They are

often referred to as tissue hormones in that they coordinate biological functions as hormones do.

A majority of hormones usually travel from their glans to the target organs through the

bloodstream. However, prostaglandins remain in their cells to act as the catalysts for functions

such as cell division, reproductive, and clotting processes. Therefore, they are some sort of

tissues hormones given that they play the role of a chemical messenger, only that they do not

move but works from where they were first synthesized.

Q3

Antidiuretic hormone (ADH) is responsible for maintaining the blood volume, urine

concentration, tissue water concentration as well as blood pressure. If an individual is

dehydrated, then their blood volume, blood pressure, and tissue water content would decrease

(Ruskin, Rosenbaum & Rampil, 2013).). Accordingly, the level of ADH in the posterior

pituitary gland would increase as this vital hormone is released to return the lost water content in

an individual’s body. It achieves such an objective by increasing the principal cell’s water

permeability in the collecting duct and distal tubule, thereby facilitating the reabsorption of

water.
